Thank you Frédéric. That are some interesting observations you made there.
I didn't mention I'm running my tests with java7 so it shouldn't be the
paint routine here, right?
Did you remove the first line from the test to run without the netbeans
propertyEditors? There's a big difference, too.

Thanks,
JBoesl

Finally, I can't say if the performance problem is due to
PropertyPanel.paint or SynthTableUI.update or another points...
The outlineView is more responsive without the NimbusLookAndFeel...

I found that the behavior is different between jdk 6 and jdk 7 because
of the property PropertyPanel.isGtk ( true with jdk 6 and false with
jdk 7).

The property is true in jdk 6 and false in jdk 7 because the parent
hierarchy of NimbusLookAndFeel changed beetween these 2 versions. I
don't know if it's a wanted behavior or if it's a bug. If you launch
your application with jre 6 then jre 7, you'll notice some differences
in the backround color of panel containing the button "...".
